A thermoelectric air-conditioning part has a thermoelectric unit performing heat absorption and heat generation by using a Peltier effect when electric power is applied, a cooling unit provided at a first side of the thermoelectric unit, and a heat dissipation unit provided at a second side of the thermoelectric unit. The module is configured so that air that is supplied from a blower is cooled by the thermoelectric air-conditioning part, passes through a cooling fin of the cooling unit, and is discharged to an interior of the vehicle through a seat cushion. The module is configured so that air that is supplied from the blower is heated by the thermoelectric air-conditioning part, passes through a heat dissipating fin of the heat dissipation unit, and is discharged through the heat dissipation path. ## Claims ### Claim 1 A ventilation module for a ventilation seat for a vehicle, the module comprising: a thermoelectric air-conditioning part having a thermoelectric unit performing heat absorption and heat generation by using a Peltier effect when electric power is applied, a cooling unit provided at a first side of the thermoelectric unit, and a heat dissipation unit provided at a second side of the thermoelectric unit;
